US 10,471,834 B2 · Hybrid vehicle and method for controlling the same

Abstract

A plug-in vehicle capable of wired-charging a battery through a charging connector using an external charger and a method for controlling the same are provided. The method for controlling charging of a vehicle configured to perform a charging operation using external power includes determining whether a refrigerant circulation device operates normally and the amount of refrigerant is normal when a temperature sensor of a charger malfunctions. When the refrigerant circulation device operates normally and the amount of refrigerant is normal, a temperature of the charger is estimated using a temperature of a heat dissipation device through which the refrigerant passes and the output of the charger is adjusted based on the estimated temperature.

Dependent claims

A method for controlling charging a battery of a vehicle configured to perform a charging operation using external power, comprising:

determining, by a controller, whether a refrigerant circulation device operates normally and an amount of refrigerant is not in an insufficient condition when a faulty operation is detected in a temperature sensor of a charger;
estimating, by the controller, a temperature of the charger using a temperature of a heat dissipation device of the controller through which the refrigerant passes when the refrigerant circulation device operates normally and the amount of refrigerant is not in the insufficient condition;
adjusting, by the controller, output power generated by the charger based on the estimated temperature;
and
stopping, by the controller, charging through the charger when at least one of the refrigerant circulation device and the amount of refrigerant is in the insufficient condition.

A vehicle for performing a charging operation using external power, comprising:

a charger having a temperature sensor and configured to charge a battery using the external power;
and
an electronic power control unit (EPCU) configured to determine whether a refrigerant circulation device operates normally and an amount of refrigerant is not in an insufficient condition when the temperature sensor malfunctions, estimate a temperature of the charger using a temperature of a heat dissipation device contained in the electronic power control unit (EPCU) when the refrigerant circulation device operates normally and the amount of refrigerant is not in the insufficient condition, and adjust output power generated by the charger based on the estimated temperature,
wherein the refrigerant circulated by the refrigerant circulation device passes through the charger and the electronic power control unit (EPCU) through a single cooling channel, and
wherein the electronic power control unit (EPCU) is configured to stop charging through the charger, when the determination result indicates that at least one of the refrigerant circulation device and the amount of refrigerant is in the insufficient condition.
